Transformer DC magnetic bias monitoring data collection system

Abstract

The invention provides a transformer DC magnetic bias monitoring data collection system comprising a data collection device, a base station device and a data processing center, wherein one end of thebase station device is wirelessly connected to the data collection device, and the other end of the base station device is wirelessly connected to the data processing center; the data collection device comprises a plurality of sensor nodes deployed on a to-be-monitored transformer, the sensor nodes collect DC magnetic bias monitoring data and send the DC magnetic bias monitoring data to the base station device, and the DC magnetic bias monitoring data comprise vibration, noise and neutral point current data; and the base station device receives and processes the DC magnetic bias monitoring data sent by the data collection device, and sends the processed DC magnetic bias monitoring data to the data processing center, and the data processing center is used for receiving and processing the DCmagnetic bias monitoring data sent by the base station device and outputting a processing result. The transformer DC magnetic bias monitoring data collection system is easy to assemble and disassemble, and check and maintain, and the wiring trouble is reduced.

Description

technical field [0001] The invention relates to the field of transformer monitoring, in particular to a transformer DC bias magnetic monitoring data acquisition system. Background technique [0002] In recent years, as more and more direct current transmission lines have been put into operation, the problem of the impact of direct current transmission on AC transformers under the single-pole ground circuit and bipolar unbalanced operation mode has become increasingly prominent: it will cause the transformer vibration and noise to increase significantly, Problems such as iron core heating and resonance affect the life of the transformer and safe production. It has become the consensus of more and more experts and scholars to monitor and study the DC bias condition of the transformer so as to solve its influence on the transformer. Contents of the invention [0003] In view of the above problems, the present invention provides a transformer DC bias monitoring data acquisiti...
